定义
口吃的特点是在发育期（即成年后）之后出现的频繁或普遍的言语节奏紊乱，超出正常变化范围，导致清晰度降低，并严重影响交流。它可能涉及声音、音节或单词的重复、延长、断字、产生障碍、过度使用感叹词以及快速短促讲话。
Speech dysfluency is characterised by the frequent or pervasive disruption of the rhythmic flow of speech that arises subsequent to the developmental period (i.e., adult onset) and is outside the limits of normal variation and results in reduced intelligibility and significantly affects communication. It can involve repetitions of sounds, syllables or words, prolongations, word breaks, blockage of production, excessive use of interjections, and rapid short bursts of speech.
